Abstract:
The embodiment relates to a wireless power transmission apparatus and a wireless power transmission method. The wireless power transmission apparatus includes a first power converting unit to generate high-frequency AC signals; a second power converting unit to generate low-frequency AC signals; a first coil receiving the high-frequency AC signals and transmitting a wireless power through a first power transmission scheme; a second coil receiving the low-frequency AC signals and transmitting the wireless power through a second power transmission scheme; and a control unit to control the first and second coils, wherein the control unit is configured to transmit a detection signal for the first power transmission scheme to a wireless power reception apparatus through the first coil, detect a reception of a first response signal corresponding to the first detection signal during a first predetermined time, determine a power transmission scheme of the wireless power reception apparatus as the first power transmission scheme in response to a detection of the first response signal, and deactivate the first power converting unit in response to no detection of the first response signal.
